Select All (using Ctrl+A key combo)... Disable browser highlighting
I have many items on a page that I set up to change the background color when a user selects them. I have implemented the Ctrl+A key combination to select all items when the user presses those keys. It works fine and selects all items as needed. However, because Ctrl+A also tells the browser to select all contents in the page, everything gets highlighted in the whole page from the browser. Is there a way to disable this behavior so it only runs my Ctrl+A command and not the browser highlighting?
